Abstract

A drawbar bracket includes a first fastening plate, a second fastening plate, and a coupling member. The coupling member couples the first fastening plate to the second fastening plate. The first fastening plate includes a first plate body, a first fastening part, and a first curved part. The first curved part couples the first plate body to the first fastening part and has a curved shape. The second fastening plate includes a second plate body, a second fastening part, and a second curved part. The second curved part couples the second plate body to the second fastening part and has a curved shape.

First claim

What is claimed is:

1. A drawbar bracket comprising:
a first fastening plate;
a second fastening plate spaced apart from the first fastening plate in a first direction;
a third fastening plate; and
a coupling member coupling the first fastening plate to the second fastening plate,
the first fastening plate comprising:
a first plate body coupled to the coupling member;
a first fastening part having a first attachment surface facing in a second direction different from the first direction; and
a first curved part coupling the first plate body to the first fastening part and having a curved shape,

the second fastening plate comprising:
a second plate body spaced apart from the first plate body in the first direction and coupled to the coupling member;
a second fastening part having a second attachment surface facing in the second direction; and
a second curved part coupling the second plate body to the second fastening part and having a curved shape,

the third fastening plate coupling the first plate body to the second plate body,
the first plate body including a first groove,
the second plate body including a second groove, and
the third fastening plate being partly disposed in the first groove and the second groove.

2. The drawbar bracket according to claim 1 , wherein
the first fastening part extends from the first curved part toward an opposite side of the second fastening part.

3. The drawbar bracket according to claim 1 , wherein
the second fastening part extends from the second curved part toward an opposite side of the first fastening part.

4. The drawbar bracket according to claim 1 , wherein
the first curved part is spaced apart from the second curved part in the first direction.

the first inner side surface is at least partly inclined with respect to the first center axis.

7. The drawbar bracket according to claim 1 , wherein
the second fastening part includes a second opening provided on the second attachment surface.

8. The drawbar bracket according to claim 7 , wherein
the second opening includes a second center axis,
the second plate body includes a second inner side surface provided to face toward the first plate body, and
the second inner side surface is at least partly inclined with respect to the second center axis.

9. The drawbar bracket according to claim 1 , wherein
the first fastening part includes a first opening provided on the first attachment surface,
the second fastening part includes a second opening provided on the second attachment surface,
the first opening includes a first center axis,
the second opening includes a second center axis,
a first distance is defined between the first curved part and the second curved part in the first direction,
a second distance is defined between the first center axis and the second center axis in the first direction, and
the second distance is longer than the first distance.

10. The drawbar bracket according to claim 1 , wherein
the first plate body extends from the first curved part away from the first attachment surface.

11. The drawbar bracket according to claim 1 , wherein
the second plate body extends from the second curved part away from the second attachment surface.

12. The drawbar bracket according to claim 1 , wherein
the first attachment surface is spaced apart from the second attachment surface in the first direction.

13. The drawbar bracket according to claim 12 , wherein
a position of the first attachment surface in the second direction is substantially identical to a position of the second attachment surface in the second direction.

14. The drawbar bracket according to claim 1 , wherein
the third fastening plate includes a third groove and a fourth groove,
the third fastening plate is coupled to the first fastening plate through engagement between the first groove and the third groove, and
the third fastening plate is coupled to the second fastening plate through engagement between the second groove and the fourth groove.

15. The drawbar bracket according to claim 1 , wherein
the third fastening plate includes a third groove and a fourth groove,
the first plate body is partly disposed in the third groove, and
the second plate body is partly disposed in the fourth groove.

16. The drawbar bracket according to claim 1 , wherein
the first plate body, the first fastening part, and the first curved part are integrally provided as a one-piece unitary member, and
